"my one and only."

choose scenes where the focal point (megumi's face) can be made to stand out. for that, i'll look for scenes against very dark backgrounds or solid backgrounds that can be darkened. when you set a gif to screen (the blend mode used for blended gifs), the light areas of that gif will stand out the most against the dark areas of the gifs underneath

choose scenes with minimal pulsing/harsh/fast movements but with fluid, soft movement (for anime since this style of animation has a lower fps). scenes with enough movement that aren't too jarring can be hard to find in shonen since there's so much action, but some of the best scenes are those "hero pose" moments where their hair blows in the wind lol (one of my fav scenes to gif is gojo in at shibuya station after choso first tries to hit him with his ct bc his blowing hair is animated so gracefully sldkfjs). in this case, i have todo's torn shirt breezing in front of megumi's face. i knew it would be a great shot to blend with bc i could darken the purple of the shirt and any gif layered above those spots would stand out against it

use layer masks and adjustment layers to "erase" distracting parts of the gif. as you can see in the video, i've erased huge chunks of some of my gifs. i often also use levels with a layer mask to darken select parts of my gif (even reducing the white point as shown in the base gif) + hue/sat to darken specific colors in a gif.

so one of my best tips for coloring is to focus on scene selection, masking, and darkening!

i know it's not a full blending tutorial, but i hope there's something here that can help you. i've also talked about parts of my blending process in these asks:
